When Matchmaking(Quick pairing) comes, make only a very very few modes

Having as many options as lichess initially will induce queues with maybe 0 in queue, resulting in a wait of forever. I suggest 2+1, 5+0, and 10+10.

I’d honestly prefer quick pairing with byoyomi clock too.

Yep, maybe 5+5 instead for a blitz mode

I'd keep longer, 30+30 to 180+180 modes out of Quick Pairing until there are way more players already.
